Patent CA-2419971-A1 (CA)
Title: Fiber optic switch and associated methods
Inventor: PRESLEY HARRY
IPC: G02B26/08
Filed: 2001-09-07
Abstract: A fiber optic switch includes a plurality of optical inputs and a plurality of optical outputs carried by a support. The switch also includes a first plurality of rotatable reflectors each being associated with a respective optical input, and a second plurality of rotatable reflectors each being associated with a respective optical output. A plurality of reflector drivers directs selected pairs of the first and second plurality of rotatable reflectors to define respective paths between the optical inputs and the optical outputs. The free-space propagating optical beam that is transferred between each input and output is formed by a micro lens producing a substantially collimated beam and therefore minimizing optical performance penalties due to the relative path length differences between various routing paths.

Title: Method and apparatus for controlling a variable optical attenuator in an optical network
Inventor: BIERMAN ROBERT MICHAEL
IPC: H04J14/02
Filed: 2003-05-20
Abstract: This invention describes a method for controlling attenuation for a variable optical attenuator (VOA) inserted in an optical path of an optical signal propagating in an optical network, comprising the steps of measuring power of the optical signal at the VOA; comparing the measured power with a target power; and if the measured power differs from the target power, changing the attenuation of the VOA, in one or more variable size intervals (VSI) so that the power of the optical signal substantially equals to the target power, wherein the VSI being a function of the measured power and target power. The method further comprises the step of comparing the measured power with a Loss-of-signal (LOS) power threshold, and if the measured power is less than the LOS power threshold, changing the attenuation of the VOA in one or more variable size intervals so that the power of the optical signal substantially higher than the LOS power threshold, wherein the size of the variable interval being a function of the measured power and the LOS power threshold. The method dynamically computes a VSI, updates the VOA setting by said VSI, and manages a combination of open and closed VOA control loops to maintain the target power attenuation of the VOA The corresponding apparatus for controlling the VOA is also provided.

Patent CA-2430256-A1 (CA)
Title: System and method for producing semi-transparent corrugated structures which automatically change their transparency to the sun's rays during the hours of the day, and the resulting structures
Inventor: MAYER YARON
IPC: F21S11/00
Filed: 2003-06-04
Abstract: Corrugated transparent or semi-transparent structures, typically from Polycarbonate or Acrylic, are typically used for creating for example various transparent or semi-transparent walls or roofs for example in large buildings or for creating greenhouses for plants. However, especially for example during the summer, this can cause overheating of the greenhouse effect, so that too much heat is caught inside, which can have undesirable effects. The present invention shows a very cheap solution for automatically regulating the penetration of the Sun's rays through such structures during the day, so that for example at noon the Sun's penetration is automatically lowered. This is preferably achieved by using a sandwich in which two external transparent plates are connected by non-transparent or at least less transparent inner walls (also called bridges) and using appropriate orientations so that when the sun rises or sets the Sun's rays can easily enter more directly and when the sun rises at noon the non-transparent or less transparent inner bridges block direct light from the Sun.

Inventor: LOCKE GORDON EVAN
IPC: H04L27/12
Filed: 2003-08-08
Abstract: An amplifier circuit for efficiently driving a tuned resonant load where the amplifier circuit controls the continuously variable resonant frequency of the tuned resonant load so as to match step changes or slower changes in the frequency of the signal with which it is being driven. The circuit includes a tuned resonant load, a driver, a controller and a feedback loop. The driver is coupled to the load and drives it with a driving signal at a frequency under the control of the controller. The controller dynamically controls the resonant frequency of the tuned resonant load in response to an error signal received through the feedback loop. The error signal represents the mismatch in phase between the resonant phase of the load current and the phase of the driving signal, or between the resonant phase of the tuning capacitor voltage offset by 90 degrees and the phase of the driving signal. The controller also controls the pulse width of the driving signal, which controls the energy transferred to the load, and ensures the pulses are centered within the half cycle of the load current to avoid advancing or retarding the phase of the load current in each half cycle.

IPC: C10G2/00

Abstract: Les sources de CO2 sont très nombreuses et variées: l'atmosphère en contient, les carbonates, etc. en contiennent aussi. Le CO2 est également le résultat de la combustion, de la fermentation, de la décomposition, bref, cette matière première est présente partout et ne pose pas de problème à quiconque veut s'en servir pour fabriquer des hydrocarbures. On n'a pas besoin de dépenser beaucoup d'argent pour en trouver. De plus, en faisant précipiter le sel sur le nickel, on améliore grandement le rendement de 1a catalyse si bien que la molécule de CO2 est brisée à 300.degree.C au lieu de 1000.degree.C. Les hydrocarbures fabriqués à partir du procédé coûtent moins cher à raffiner car ils ne contiennent pas de soufre. Ils sont finalement rentables et vendables parce qu'ils sont très en demande comme l'essence automobile, l'huile à chauffage, le diesel, les huiles lubrifiantes, le mazout, l'asphalte, le goudron, etc. Si on est équipé pour fabriquer du CO2, pour capter les biogaz ou les fumées d'usines ou, si on dispose involontairement de CO2, on peut rendre ce gaz indésirable très utile à l'économie. En effet, au lieu de se débarrasser du CO2 en pure perte, on peut 1e recycler en hydrocarbures et contribuer ainsi à nettoyer l'atmosphère tout en se procurant une source de revenus supplémentaires.Comme le CO2 est une ressource renouvelable, le procédé apporte sa contribution à la lutte contre les émissions de gaz à effet de serre et favorise le développement durable.
